A nickel strip isa highly conductive strip of nickel or nickel-plated steel used to create secure, low-resistance connections between lithium battery cells for assembly into packs.It enables efficient power transfer, minimizes voltage drop, and provides the necessary structural integrity and flexibility for these packs.Available in various widths and thicknesses, nickel strips are essential for building custom lithium-ion and LiFePO4 battery packs used in applications like electric vehicles, power tools, and energy storage systems.
